Antibiotics Home > Amoxicillin Dosage

Your healthcare provider will calculate an appropriate amoxicillin dosage for you based on several factors, including your weight, the type of infection, and the type of bacteria causing the infection. It is important to space out your doses of amoxicillin as evenly as possible, such as every 12 hours for twice-daily doses or every 8 hours for thrice-daily dosing.

An Introduction to Amoxicillin Dosage

The dose of amoxicillin (Amoxil®, Moxatag) that your healthcare provider recommends will vary, depending on a number of factors, including:
  • Your age and weight
  • The type of infection and bacteria
  • Other medical conditions you may have
  • Other medications you may currently be taking.
As is always the case, do not adjust your dosage unless your healthcare provider specifically instructs you to do so.

Amoxicillin Dosing for Adults, Children, and Infants

There is no "standard" amoxicillin dose that is recommended for all situations. Your healthcare provider will calculate the appropriate dose taking into account several factors, including your weight, the severity of the infection, the type of the infection, and the type of bacteria causing the infection. Be sure to follow your healthcare provider's dosing instructions carefully. Try to space the doses out as evenly as possible (every 12 hours for twice-daily doses or every 8 hours for thrice-daily dosing).
Be sure to finish your prescription, even if you start to feel better. Stopping amoxicillin too soon could lead to the development of antibiotic-resistant bacteria.

General Information on Dosing With Amoxicillin

Some considerations for people taking amoxicillin include the following:
  • Amoxicillin comes as capsules, tablets, chewable tablets, pediatric drops, and oral suspension (liquid). For most conditions, it is usually taken by mouth two or three times a day (except for gonorrhea, which is treated with a single, one-time dose). One long-acting product (Moxatag) is taken just once a day.
  • For most amoxicillin products, you can take amoxicillin with food or on an empty stomach. If it bothers your stomach, try taking it with food. However, Moxatag should be taken within one hour after finishing a meal.


  • Be sure to shake the oral suspension or pediatric drops well before each dose. The suspension and drops taste better if stored in the refrigerator.
  • A dose of the oral suspension or pediatric drops can be added to formula, milk, fruit juice, water, ginger ale, or cold drinks if necessary. The mixture should then be taken immediately and completely.
  • For the medication to work properly, it must be taken as prescribed. Amoxicillin will not work if you stop taking it too soon.
  • If you are unsure about anything related to your dosage or amoxicillin dosing in general, please talk with your doctor, nurse, or pharmacist.
